| Outline of Final Research Achievements |
The aim of this study is to develop a novel method to infer the semantic contents of the visual perception and visual imagery from the ECoG signals and MEG signals. We recorded both of the ECoG and MEG signals while the subjects were watching the images of 3 or 9 categories. The developed decoding method successfully inferred the categories from the ECoG or MEG signals. Moreover, the same decoding method successfully inferred the semantic contents of the visual imagery which the subject imagined freely. These results are expected to be applied for the severely paralyzed patients to improve their communication ability and the quality of their lives.
